BURNER FOR OlL-STOVES.

SPECIFICATION forming part of Letters Patent No. 242,183, dated May 31, 1881.

Application filed March 21, 188]. (No model.)

To all whom it may concern:

Be it known that I, LEWIS F. BETTS, of Morton, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvementsin Burners for Oil-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates especially to that class of burners employed in stoves used for domestic purposes-either cooking or heating-and J lvherein liquid hydrocarbons constitute the uel.

The object of this invention is to produce a simple, cheap, and effective burner, not liable to get out of order, easy to keep in perfect working condition, and constructed in such a manner that any'portion thereof may be speedily removed and a new part substituted therefor, obviating the necessity of replacing the whole burner when parts become worn or broken. To attain this end'niy invention involves certain novel and useful combinations or arraugements of parts and peculiarities of construction and operation, all of which will be hereinafter firstfully described, and then pointed out in the claims.

In the drawings, Figure 1. is a top or plan view of my improved burner, wherein are employed four wick-tubes. Fig. 2 is a side elevation, partly in section, of the burner, showing the method employed for securing the various parts in place and the interior portions of the wick-tubes and base of the burner. Fig. '3 is a perspective view of a portion of one side of the removable wick-tube, and Fig.4 is a like view of the opposite side. Fig.5 is a perspective view of a portion of a completed wicktube constructed in accordance with my improvements. Fig. 6 is a perspective view of a portion of the guide-plate for holding-the wicktubes and ratchet-shafts in place upon the base of the burner; and Fig. 7 is a like view of a portion of the base of the burner, showing the location and arrangement of the slots therein and the removable ratchet-shaft.-

lamp-pot by means of screws or bolts.

Like letters of reference, wherever they occur, indicate corresponding parts in all the figures.

A is the base of the burner, constructed of cast iron or any other preferred material. This base may be of such size and shape as to conform to the oil pot to which it is to be attached; or, if desired, it may be made to form the entire top of the oil-pot, and be cast therewith. In the drawings I have shown the base as prepared for the reception of four wick-tubes, although one or any desired number may be used, and as provided with perforations a at each end for the purpose of securing it to the When thus constructed it will be found advantageous to place suitable packing material between the oil-pot and base A before securing, in order to insure a perfectly tight joint and prevent the oil from spilling. When the oil-pot is constructed of sheet metal or any equivalent material, base A may be united thereto by solder or in any other preferred manner. At each point in base A where a wick-tube is to be placed the metal is cut away, as shown in Fig. 7, leaving a slot extending across the base from side to side, with a rounded depression at either end thereof in the flange upon the base, forming bearings for the ratchetshafts. Theseslots are made of such width as to permit the shaft and the ratchets thereon for raising and lowering the wick to pass freely through. The shafts are provided with shoulders to prevent slipping through the bearin gs or lateral movement.

B is a metal plate, cast or otherwise formed to fit over the wick-tubes and extend down a short distance upon each side of the elevated portion of base A, forming the wheel-house for the ratchets. The slots in plate B are the same in n'umberand location as those in base A, but are more narrow, so as to nicely fit around the wick-tubes,and shorter, not quite reaching the edges of the plate upon each side. I) b are bolts or screws passing through perforations in plate B and base A, for the purpose of securing the parts together. Instead of using a. bolt and nut, the perforations in base A may be screw-threaded for the reception of the bolt or screw b.

In forming the wick-tubes C, I employ two portions of sheet metal the required thickness, the same being bent by suitable dies in such a manner that each wall consists of a double thickness of metal, as plainly shown in Figs. 3, 4, and 5, the position of the interior portions being indicated by the dotted lines. Upon one side of the wick-tube the interior portion of metal is bent outward, with the exterior portion at the bottom of the tube to form a supporting-base. Upon the opposite side only the exterior thickness of metal is bent outward to form the supporting-base, the inner part extending down below the wick-tube through the slot in base A, and, beingfree at each side, it constitutes a flexible spring, S, for the purpose of pressing the wick against the .ratchets r. If desired, instead of forming the removable wick-tube of sheet 1netal,it may be cast of the same shape, having the supporting-flanges at each side at bottom and the part. extending below the wick'tube upon one side. In this case the part below the wick-tube will be rigid, but it will he found equally etlicient for press ing the wick against the ratehets.

P is a plate, of tin or other suitable metal, stamped or otherwise formed to fit snugly over the base A and extend a short distance down upon each side of the raised portion of the base. It is provided with openings 1), corresponding in size and number to the wick-tubes, and also with slots (1 in the bent-down portion of each side for the reception of the ratchet-shafts It. It the bearings for the ratchet-shafts were simply cast both in base A and plate B, it would be found in practice to be of great inconvenience in adjusting and operating the shafts, as it is impossible to accurately cast these bearings in rough metal; and if the shafts were applied in bearings formed in this manner there would be too great play, allowing the ratchets to be forced away from the wick, or the shaft would be cramped, so that it could not be turned in either direction. By interposing plate 1 between base A and plate B I overcome all these difliculties. The slots in said plate, being formed by a die, are always uniformly located, rendering the action of the ratchet-shafts accurate and perfect. It the slots d become worn by long-continued use, all that is necessary to remedy the evil is to remove the old plate and substitute a new one therefor.

As heretofore constructed all burners for oil-stoves have been liable to get out of order or become disarranged by continual use, necessitating an entire new burner in order to place the stove in working order; but by use of my improved device this expense is rendered unnecessary. All the parts of the burner, being made by machinery, are interchangeable, and should any part become worn or quickly replaced at a trifling cost, and must always accurately lit the old portions of the burner.

In assembling the parts of the burner for use, base A is first secured to the top of the oil-pot and the ratchet-shafts placed in position in their respective bearings. The wicktubes are then placed in the slots in base A, the spring or straight portion of the wick-tube projecting downwardly through the slot upon one side of the ratchets. Plate 1 is next passed down over the wick-tubes and ratchetshafts, plate B placed thereabovc, and the whole secured iirinlyin place by means of the bolts or screws 1/, as before explained. The wick-tubes are held against displacement and the shafts of the ratchets accurately adjusted, so that the springs S will press the wicks against them, thereby insuring instant response of the wick to any motion applied to the ratchet-shaft. It will thus be seen that my improved burner admirably answers the various uses and purposes for which it is intended.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-
